Worked on privacy and data management enhancements in the duckduckgo/privacy-configuration repository, focusing on strengthening user privacy controls. Developed new data-clearing settings flags and introduced a burn single tab feature, both designed to give users more granular control over their data. Ensured safe deployment by gating these features behind a minimum supported version of 7.207.0, allowing for compatibility across different environments. Utilized configuration management and data handling skills, working primarily with JSON to define and manage settings. Established internal enablement and rollout mechanisms, enabling controlled feature availability and supporting scalable privacy improvements prior to broader public deployment.
